问题描述:
done,been是什么,过去分词和过去式有什么区别
答
原型 过去式 过去分词
do did done
be was/were been
过去式一般作动词用的,作谓语的,有时也是助动词,比如did not go,而过去分词一般做定语状语,有时也会作表语,有时也表示被动,当然了,过去分词在完成时态中也可用,比如have done ,have been 等
答
过去分词表示被动,与have/had一起构成完成时态。过去式在句中表示动作发生在过去。只能是:I have been seen.I have seen it.I saw it.I had seen it.I had been seen.
答
do,did,done;be(is,are),(was,were),been.是不是这样?
